Definitions
- the clasp which is most known and used commercially comprises a hollow ring in which is mounted a plunger which slides inside the ring and is biased by means of a spring, also located inside the ring, to close a small open arc formed in the ring.
- This kind of clasp has major disadvantages.
- the plunger and the spring which are located inside the ring, do not receive sufficient ventilation and corrode easily due to the humidity of the skin.
- the ring itself is also subject to be easily flattened or twisted out of shape. The result is that the plunger becomes stuck and the clasp stays half or fully open, leading possibly to the loss of a valuable piece of jewelry.
- Another type of clasp used in jewelry has the form of pincers having a jaw provided with several pairs of teeth which overlap each other to partially surround the ring at the end of the chain. This ring can easily be caught in a single pair of teeth and, if too much tension is applied to the chain, the pair of teeth may break.
- first element having a main body and a jaw in the form of a hook which is integrally formed with the main body of this first element
- second element also having a main body and a jaw in the form of a hook integrally formed with the main body of the second element.
- the jaws of both the first and second elements are tapered: one to the left and the other to the right, thereby mutually lapping each other.
- Means are provided to pivot the main bodies relative to each other, such that the tapered surfaces of the jaws define contacting faces.
- a spring means is provided to bias the jaws of the first and second elements into movement towards each other.
- the interior portion of the hook of each jaw has a radius of curvature corresponding to the radius of curvature of a ring normally provided at one end of small jewelry chains, and the width of each of the jaws is sufficient to receive a substantial portion of the circumference of the ring.
- Such construction prevents the deformation of the ring as well as breakage of the jaws when excessive tension is applied to the ring and also prevents wearing-out of the latter.
- the cavity formed by the hooks of the jaw is of such construction that the hooks surround opposite surfaces of the ring in taut configuration of the chain, thus preventing the opening of the clasp in such configuration.
- the clasp is therefore very safe.
- FIG. 1 is a perspective view of the clasp according to a first embodiment of the invention in closed configuration
- FIG. 2 is a perspective view of the clasp of FIG. 1, in open configuration
- FIG. 3 is a side view of the clasp of FIG. 2 showing a ring inserted in the jaws;
- FIG. 5 is a rear elevation of the clasp
- FIG. 7 is a bottom plan view of the clasp.
- FIG. 8 is a side elevation of the front portion of the clasp in open configuration and modified in accordance with a second and preferred embodiment.
- jaws 14 and 22 are tapered so that, when in closed lapped configuration, the sum of their widths does not exceed the maximum width of the clasp.
- the cavity formed by closed hooks 16 and 24 is of such dimension so as to completely surround the ring when the chain is taut. In this manner, the clasp cannot open by itself because the two hooks 16 and 24 surround opposite surfaces of the ring. To open the clasp, it is thus necessary to push the ring out of the cavities formed by the hooks 16 and 24.
